MANUFACTURE OF OX-SHOES.

SPECIFICATION forming part of Letters Patent No. 261,254, dated July 18,1882.

I Application filed February 20, 1882. (N model.)

' Plantsville, in the county of Hartford and State of Connecticut, haveinvented certain new and useful Improvementsin Dies forMaking Ox-Sh'oes,of which the followingisa specification. 7

My invention relates to improvements in dies for manufacturing ox-shoes,in which a bar of the proper size is first bent over a former into acurved form without otherwise changing the shape of the bar. Then thecurved end of the bar is placed over and forced into a die to shape theshoe, which is then forced through a trimming-die to remove the fin orsurplus metal, and thus punch the shoe from the bar, and finally theshoe is subjected to a gang of dies and punches forpunchingthenail-holes at a single blow, all of which steps areperformed. successively by means of my dies, while the iron is hot, andat a single heat.

The objects of my invention are to produce ox-shoes with littleexpenditure of labor and fuel, thereby producing the same faster and atless expense than heretofore. I attain these objects by the mechanismillustrated in the accompanying drawings, in which- Figure l is a sideelevation of the former and swaging-die. Fig. 2 is a plan view of thesame. Fig. 3 is a side view of the bent bar ready for swaging. Fig. 4 isa side view of the bar with a shoe swaged on the end of the same. Fig. 5is a' plan view of the shearing, trimming, and nail-hole dies; and Fig.6 is an under side view of the upper members thereof.

Heretofore in the manufacture of machineforged ox-shoes it has beencustomary to prepare special blanks, which were reduced in size at theend which was designed to be formed into the toe end of the shoe, and tosever said blanks from the bar before subjecting them to the die whichswaged them into the form of a shoe. I propose to do away with all suchblanks, and to swage the shoe directly from the bar without firstreducing the size of the bar in cross-section.

tion with parallel toe and heel calks, for which I have previouslyobtained Letters Patent.

A designates the block or brd in which the swaging-die B is secured.

In the upper face of the die B is a depression which in form is thecounterpart of the shoe intended to be produced. This die is used inconnection with a plain-faced drop or hammer, which I considerunnecessary to show.

Upon one side of the block A, I place a forming-block, O, the upper faceof which is curved in the form which it isintended to give to the barfrom which the shoe is swaged. This forming-block I make attachable anddetachable, so that different forming-blocks may be secured to the blockA'whendesired to form a different size or style of shoe.-

Just above the end of the forming-block O a lug, b, is formed on theside of the block A, through which an adj listing-screw, 0, passes.

I select afiat bar of the proper size and bring it to the proper heat,and then place the end over the forming-block C and under the adjusting-sorew 0, when the free end of the bar is depressed and the otherend bent ed gewise to conform to the shape of the forming-block,substantially as shown in Fig. 3. The screw 0 may be adjusted toaccommodate bars of dif' ferent widths, and also to slightly vary thecurve at the end of the bar, by letting it up a little away from theface of the forming-block. This screw forms an adjustable mechanism forholding the end of the bar while it is being bent. The bar so bent isthen placed over the die B, substantially as indicated by broken linesin Fig. 2, and the plain-faced hammer strikes the bar to force it intothe depression in the die, the surplus metal being forced outward andleft in the form of a fin, a. The bar as it appears when taken from thisswagingdie is shown in Fig. 4.. The curved bar is not wide enough tocover the die, and its end need not be placed thereon far enough tocover the toe-depression,because when the iron is struck it is drawn outendwise and forced sidewise, so as to fill the die, even though the endof the bar as placed thereon may fall back about half an inch from thetoe end of said die. The headingdie B is beveled off upon its upperfront corner from near the depression in order to prevent the bar frombeing struck by said die for any great distance outside of thedepression. The front corner of the trimming-die D is beveled in likemanner. The bar, with the shoe swaged thereon, as shown in Fig. 4, isnext placed over the trimming-die D, which is the female member of acutting-die whose contour is substantiallythe same as that of the shoeand the depression in the die Bin which the shoe was formed. Said die Dand its punch D are designed for use in an ordinary power-press, andwhen the bar, with the shoe swaged thereon, is properly seated over saiddie the punch is caused to descend and force the shoe through said die,thereby punchingit from the bar. If any portion of the fin a stillremains on the bar it is placed between the shears or cutters f f (whichare of ordinary form) and cut off by another motion of the press, whenthe bar is ready to be placed in the fire again for reheating. The shoewhich has been passed through thetrimming-die is then picked up with apair of tongs, and the nail-holes are punched at one blow by subjectingthe shoe to the gang of dies and punches n n n n and 0 0 0 0 and givingthe press another motion.

By swaging the shoe and punching it from the bar it can be handled muchmore rapidly and conveniently than could be the case if previouslysevered blanks were used which had to be picked up with the tongs forsuch operation, and therefore I am enabled to perform all of theforegoing operations to produce a shoewhile the iron is hot and by asingle heat.

The cutters ff, dies and punches D D n a at n 0 0 0 0 are all mountedupon the die-blocks E E, so as to secure them all in one and the samepress, which is conveniently located with reference to the bending andswaging apparatus. The cutters ff can be used to cut off the bar at anytime or at any desired point.

The punches 0 0 0 0 I set in a punch-box for convenience of making andrepairing the same.

The take-ofis for the dies at n n n are shown at r a", Fig. 5.

I claim as my invention 1. The block A, having the swaging-die B uponits upper side, the attachable and detachable forming-block O, and theconfining lug and screw 1) 0 upon one of its Vertical sides,substantially as described, and for the purpose specified.

2. The series of dies for forming oX-shocs, consisting of the die-blockA, swaging-die B, and former G, secured thereto, and the diebloeks E E,having thecutters ff and dies and punches D D n n n n 0 0 0 0,substantially as described, and for the purpose specified.

3. The die-blocks E E, having the cutters f fand dies and punches D D nn a n 0 0 0 0, substantially as described, and for. the purposespecified.
